I just traded up from an '08 R32 to a 135i and the difference is dramatic and amazing. The car is so complete as a small performance coupe and confidence inspiring on the road. The biggest difference is the car makes no excuses, and dosn't require a trip to an APR tuner to get Stage I to feel complete. DCT is very similar to DSG, but I don't expect to get a letter about recalls for the transmission any time soon. I love the torque band of the N55 engine, and with the DCT it feels like it is never caught in the wrong gear, just a solid thrust of acceleration when you stomp he go pedal. Remember that BMW is very anti tuner, so don't be the guy that loses his warranty when something bad happens! IMHO, the 135i is a superior performance coupe that will not disappoint you!!
